Top-Emitting Chip SMD LED, also known as TEC-SMD LED, has become an essential component in various lighting applications. With its compact size, high efficiency, and excellent heat dissipation, it has revolutionized the LED industry. This article aims to provide an in-depth introduction to TEC-SMD LED, covering its working principle, advantages, applications, and market trends.

Working Principle of Top-Emitting Chip SMD LED

The TEC-SMD LED is a type of surface mount device (SMD) LED with a top-emitting chip. Unlike traditional LEDs, which emit light from the sides or bottom, TEC-SMD LEDs emit light from the top surface of the chip. This unique design allows for better light distribution and higher luminous efficiency. The working principle of TEC-SMD LED is based on the semiconductor material. When an electric current passes through the semiconductor material, electrons and holes recombine, releasing energy in the form of photons. The color of the light emitted depends on the energy band gap of the semiconductor material. The TEC-SMD LED typically consists of a chip, a lead frame, a lens, and a reflector. The chip contains the semiconductor material and emits light. The lead frame serves as a mounting structure for the chip, and the lens and reflector help to shape and direct the light.
